Hysteresis loops measurements have been performed for various GdBa 2Cu3O7 high temperature superconducting samples hydrogenated at 200-500 K. Magnetic measurement at low temperatures (close to 4 K) revealed initial gradual increase in the pinning force and critical current density at low annealing temperatures. These measurements also revealed non-monotonic changes in the pinning force close to the transition temperature. Very little reduction in the transition temperature has been observed in samples hydrogenated below 300°C.
